Perceived Magnitude and Power Consumption of Vibration Feedback in Mobile Devices
This paper reports a systematic study on the perceived magnitude of vibrations generated from a vibration motor fastened on the user’s thenar eminence and its electric power consumption. The vibration motor is widely used in mobile devices for vibration feedback due to its small size and inexpensive price. However, a critical drawback of the vibration motor is that the amplitude and frequency of vibrations generated from it are correlated due to its operating principles that allow only one control variable (applied voltage). Motivated by this fact, we have investigated a relationship between the perceived magnitude of vibrations produced by the motor and its power consumption with the applied voltage as a common parameter. The results showed that using more power does not necessarily increase the sensation magnitude, which indicates vibrations of the same perceived magnitude can be rendered while extending the life span of a mobile device battery.
